`Understanding (vignana) is better than reflection. Through understanding we understand the Rigveda, the Yagur-veda, the Sama-veda, and as the fourth the Atharvana, as the fifth the Itihasa-purana, the Veda of the Vedas, the Pitrya, the Rasi, the Daiva, the Nidhi, the Vakovakya, the Ekayana, the Devavidya, the Brahma-vidya, the Bhuta-vidya, the Kshatravidya the Nakshatra-vidya, the Sarpa and Devagana-vidya, heaven, earth, air, ether, water, fire, gods, men, cattle, birds, herbs, trees, all beasts down to worms, midges, and ants; what is right and what is wrong; what is true and what is false; what is good and what is bad; what is pleasing and what is not pleasing; food and savour, this world and that, all this we understand through understanding. Meditate on understanding.
